3M 7100112948 Cubitron Ii 987C Fiber Disc 36 Grit 7 in

Product Description

The 3M 7100112948 is a Cubitron II 987C coated fiber disc engineered for medium to heavy-duty grinding, weld grinding, and beveling applications. At 7 inches in diameter and 36 grit, this disc combines 3M Precision-Shaped Grain with a stiff fiber backing and strong resin bond to deliver a high cut rate with less applied pressure. An integrated grinding aid reduces surface temperatures during operation, making it suitable for heat-sensitive alloys. The disc is rated at 8,600 rpm and weighs 0.15 pounds. Installation and use are typical for angle grinder and pressure-assisted or robotic grinding setups used by fabricators and metalworking professionals.

This fiber disc is built for demanding industrial and fabrication environments where weld grinding, stock removal, and edge beveling require both speed and disc longevity. It is sold individually and fits standard 7-inch fiber disc backing pads. The Precision-Shaped Grain stays sharp longer than conventional abrasive grains, which means more parts completed per disc and fewer changeovers during production runs. Its stiff fiber backing resists tearing under high-pressure applications, making it appropriate for both manual and robotic grinding setups.

Key Features

• 3M Precision-Shaped Grain delivers a fast cut rate and maintains sharp cutting points throughout disc life
• Stiff fiber backing with strong resin bond resists tearing under heavy grinding pressure and beveling loads
• Integrated grinding aid minimizes heat buildup, suitable for heat-sensitive alloys and stainless applications
• Rated at 8,600 rpm for use with standard angle grinders and pressure-assisted equipment
• Longer disc life and fewer changeovers reduce downtime in high-production and robotic applications

Compatibility

Designed for use with 7-inch fiber disc backing pads on angle grinders and pressure-assisted or robotic grinding systems in medium to heavy-duty metalworking applications.

Installation Notes

This disc is installed and replaced by fabricators, metalworkers, or maintenance technicians operating angle grinders or pressure-assisted grinding equipment. Before changing discs, power down and disconnect the grinder from its power source. Verify the backing pad diameter and arbor size match the disc before mounting. Always confirm the tool's rated rpm meets or exceeds the disc's 8,600 rpm rating before use, and inspect the disc for damage prior to each installation.
